Hello, I'm trying to declare an extension method inside an interface and then call that method, however, this doesn't seem to work. Is this a known limitation? I couldn't find anything that mentioned this on Kotlin docs.
```interface LazyGridForm {

    fun LazyGridScope.invoke()

}

fun LazyGridScope.form(lazyGridForm: LazyGridForm) {
    lazyGridForm.invoke()
}```

you defined  `invoke()`  as an extension on `LazyGridScope` so you cannot call it as a member function of `LazyGridForm`

so this will work but is not what you intended.
```fun LazyGridForm.form(lazyGridScope: LazyGridScope) {
    lazyGridScope.invoke()
}```

As a workaround you can write
```fun LazyGridScope.form(lazyGridForm: LazyGridForm) {
    with(lazyGridForm) { this@form.invoke() }
}```
